Scrivener for iOS is finally out so here are 3 ways - other than for novel writing - that it has become a vital tool for me.
1. Collating articles
A .scriv file is a wonderful way to collect and archive articles, whether older ones or current articles. You can drag in Word docs and text files and it stores them all as .rtf documents. It's quick to flick back and forth between different items, and search words and phrases.
2. Client projects
I create a .scriv for each client I work with. This enables me to collate briefs, written work and any background research and information, as well as correspondence and teleconference notes. It's so much easier having it all in one place, rather than as a desktop folder with a range of different items inside it.
3. Collecting & compiling
Recipes, poems, information, snippets: you can aggregate whatever text files you like inside a .scriv - even images (in the Research section). This makes it easy to export a specific set of recipes, for example, as an eBook or pdf, selecting only those you want to export.
In summary, Scrivener works just as well as a filing and easy (multiple type) document viewing solution as it does as writing software. It will be the best 45 bucks you ever spend.
Even if you decide not to buy it after the free demo expires, you can still access your files. They're bundled inside the .scriv (you can just Unpack it) as .rtf files. You won't lose anything.
